ZTE says it will soon begin sales of an unlocked version of its Firefox OS-based ZTE Open handset on eBay US and UK for $80, following its launch in Spain, Venezuela, and Colombia. In related news, Samsung is once again rumored to be slowing Tizen OS development, and Mozilla released a new version of the Firefox for Android Beta with WebRTC real-time communications support. Rising Android smartphone vendor ZTE continues to test the market on another Linux-based mobile operating system: Mozilla’s Firefox OS. The Firefox OS-based ZTE Open will go global with a release coming “soon” to eBay’s U.S. and U.K. online stores, starting at $80 and 60 Pounds, respectively. The phone is unlocked, so it can be used just about anywhere, and is available only in orange coloring.The unlocked orange model offers preloaded Facebook and Twitter apps, the Nokia HERE mapping application, and of course, the Firefox Web browser and access to the Firefox Marketplace app store. Here, users can download apps, including eBay, Badoo, Terra, Kayak, The Weather Channel, TMZ, AOL, Wikipedia, CNNMoney, Huffington Post, TIME, Airbnb, Time Out, and SoundCloud apps.The ZTE Open was the first commercial Firefox OS phone to ship, when it was launched in Spain by Telefonica in early July. On Aug. 1, Telefonica announced that it had begun selling the phone along with its similarly spec’d Firefox OS cousin, the Alcatel One Fire, in Colombia and Venezuela. The One Fire was originally launched in Poland by Deutsche Telekom.
